The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) that includes one or more refractive angularly-varying phase members, each varying depths of focus of the apparatus so as to provide an extended tolerance to misalignments of the apparatus. Each refractive angularly-varying phase member has a center at a first meridian (e.g., the intended correction meridian) that directs light to a first point of focus (e.g., at the retina of the eye). At angular positions nearby to the first meridian, the refractive angularly-varying phase member directs light to points of focus of varying depths and nearby to the first point of focus such that rotational offsets of the multi-zonal lens body from the center of the first meridian directs light from the nearby points of focus to the first point of focus.

An intraocular lens comprising an optic and four haptics extending from the optic, each haptic having a proximal end meeting with the optic at differing points about a periphery of the optic. The four haptics are arranged into a first pair comprising two arcuate haptics with curvature orientated toward each other such that a distal end of each of the two haptics of the first pair are in nearer relation than their proximal ends; and, a second pair comprising two arcuate haptics with curvature orientated toward each other such that a distal end of each of the two haptics of the second pair are in nearer relation than their proximal end.

Software for calculating an astigmatism treatment is operable upon execution to perform the following steps: receiving biometric information for a patient; determining based on the biometric information an astigmatic correction comprising at least one of (a) a position for one or more limbal relaxing incisions and (b) a power and an orientation for a toric intraocular lens (IOL); generating an output comprising the astigmatic correction; receiving a selection of a different ratio of astigmatic correction attributable to the one or more limbal relaxing incisions and the toric IOL; determining an updated astigmatic correction including at least one of (a) an updated position for the one or more limbal relaxing incisions and (b) an updated power and/or orientation of the toric IOL.

An ophthalmic marking device is provided herein for marking a patient's eye. The device may include a handle and a tip with a tip element, a first portion of the tip element protruding from the tip to be exposed. The tip element is electrically conductive to resistively generate heat with electrical flow therethrough. A source of electrical power is associated with the device and electrically coupled to the tip element. The source of the electrical power and the tip element are configured to cause the first portion of the tip element to have a temperature in a range of 250° F.-450° F. Advantageously, the subject invention provides for a relatively low-cost device for marking a patient's eye and allows for creating a less traumatic marking on a patient's eye as compared to higher temperature electrocautery devices.

To realize a toric ophthalmic lens including an edge that makes it possible to design a lens contributing to secondary cataract prevention without deteriorating a degree of freedom of lens design. The toric ophthalmic lens is a toric ophthalmic lens in which, in a top view of an optical portion, a substantially flat portion having a substantially fixed edge thickness of the optical portion is provided to overlap a steep meridian of a toric surface of the optical portion.

A foldable intraocular lens, made from a foldable soft material, for implantation in a ciliary sulcus of an eye having an iris, is provided with an optically active lens part having an optical axis and at least four haptics unitary with the optically active lens part and uniformly spaced about a periphery of the optically active lens part. The optically active lens part having a non-convex rim between any two neighboring haptics being free from surface irregularities that interfere with the iris. Each haptic comprising a closed loop, and a shoulder connecting the loop with the optically active lens part, the haptic loops being elastically deformable in a plane perpendicular to the optical axis of the optically active lens part in a direction toward the optically active lens part.

In a toric lens comprising a toric surface having a fine uneven structure, the fine uneven structure includes a plurality of holes, the plurality of holes have a hole depth H and a surface opening diameter φt which satisfy an expression of 0.3≤H/φt≤0.6, and (a) the plurality of holes have a hole structure having a cylindrical shape on a bottom surface side and a circular truncated cone shape having an opening diameter increasing toward a surface side, or (b) an angle θ formed between an opening portion and the surface of the plurality of holes satisfies 78°≤θ≤85°.

Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing a piggyback lens which in combination with the cornea and an existing lens in the patient's eye redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The piggyback lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the piggyback lens can be configured to improve or reduce optical errors at the location on the peripheral retina. One or more surfaces of the piggyback lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles. One or more surfaces of the piggyback lens can be faceted.

Provided herein are devices used to reconstruct a natural lens capsule after a cataract surgery. The device has a ring-shaped rigid component, a ring-shaped flexible component and a groove disposed on an inner surface of the rigid component. The rigid component has a distal end attached to the ring-shaped flexible component and a proximal end that lies against Wieger's ligament when fitted within the natural lens capsule. The ring-shaped flexible component has a proximal end that is attached to the distal end of the rigid component and a distal end that contacts an anterior surface of the natural lens capsule when fitted therein. The groove is disposed to receive optics of an intraocular lens and/or the ledge is disposed to secure haptics thereof.

The invention relates to a device and a method for displaying the axis of astigmatism of an eye, in which an observation unit is used to observe the eye and, using a display unit, the orientation of the axis of astigmatism of the eye is displayed. A sensor unit generates sensor data which indicate a modification to the alignment of the observation unit relative to the eye. A calculation unit updates the displayed orientation of the axis of astigmatism with the aid of the sensor data, and issues it as the current orientation of the display unit.
